Abstract: Sterilization of mushroom growing substrates is energy intensive process for mushroom cultivation. Fuelwood may be replaced by spent substrates for hot steam generation. However, combustion of spent substrates directly in an open furnace is troublesome due to low efficiency and excessive smoke emission. Alternative conversion of the by-product to provide clean energy should be studied. In this work, recycling of spent mushroom substrates through gasification to provide heat for sterilization of substrate bags has been investigated. The findings showed that spent substrate was successfully used as biorenewable fuel in a gasifier. Satisfactory operation was obtained. Gasification of spent substrate could provide required thermal input, with clean energy to the local mushroom farm. Thermal efficiency of about 20% was achieved, compared to 5% from existing furnace. Preliminary economic analysis showed that the farm can save around $300 a month, with simple payback peri!
od to positive cash flow of less than 12 months.
